The other day, I saw a familiar lament on Reddit r/relationships. “My husband does not brush his teeth,” a 41-year-old woman wrote, “and I’m at my wits end.” She describes his horrible breath, how she has told him she doesn’t want to kiss him, and that when she nags him enough to do something about it, he swishes mouthwash around for a second and thinks that’s enough.

Gross. Husbands, would you want to kiss your wife if her mouth was disgusting? Brush your teeth. Some elements of attractiveness are beyond your control, but you’ve got a responsibility to be your best you for your spouse. Your body will never be perfect, but that’s no excuse to neglect what you’ve got.

Maybe tooth-brushing is pretty obvious, but the test of “would you put your own mouth there?” is applicable to any part of your body that you’d like your wife to put her mouth on.
